This project explored how agricultural waste in Northern Ireland—particularly livestock manure and grass silage—can be transformed into clean energy. Led by Queen’s University Belfast in collaboration with AFBI, EnerChem Solutions, Phoenix Energy, and AgriAD, the research aimed to support the shift away from fossil fuels by using local resources to produce renewable gas.
The team developed detailed maps showing where agricultural resource is most available and how it could be used to generate biomethane, a renewable alternative to natural gas. They also examined how combining existing technologies like anaerobic digestion and pyrolysis could help reduce greenhouse gas emissions while recovering valuable nutrients like phosphorus.
The findings suggest that Northern Ireland could meet up to 80% of its annual gas demand using biomethane from manure and silage. This approach not only helps tackle climate change but also addresses environmental challenges linked to nutrient pollution in soil and water.
Importantly, the project highlights how farming and energy sectors can work together to build a more circular economy—where waste is reused, emissions are reduced, and communities benefit from cleaner energy and new job opportunities. The research provides a strong evidence base for policymakers, industry leaders, and local communities to make informed decisions about sustainable energy and agricultural practices.
